Manufacturing of GF/PP warp-knitting fabrics reinforced polypropylene composite materials

  • Continuous glass fiber reinforced polypropylene (GF/PP) composite material were manufactured with a new kind of warp-knitting fabrics in two different forms by thermoforming. The microstructure of impregnation quality of the composite material was observed with the scanning electronic microscope (SEM) and substantiated by the results of void content measuring. The fabric structure effects on impregnation quality were investigated. The composite mechanical properties influencing factors and change tendency were also discussed. The two different fabric forms were compared. The results show that it is feasible to manufacture thermoplastic composite materials with warp-knitting fabrics; different knitting forms lead to different impregnation quality which directly influences composite mechanical properties.
